A system and method for notifying a remote device of a low battery capacity condition in a wireless communications system is disclosed. A detector monitors the capacity of the battery in a wireless device receiving operational power from the battery for a low capacity condition. A control system coupled to the detector sends a low battery capacity status signal to the remote device upon detection a low battery capacity condition. While the battery is in a low capacity condition, communications between the wireless device and the remote device may be maintained until the low battery capacity condition is corrected.
Legal claims defining the scope of protection, as filed with the USPTO.
1. A method for notifying a remote device of a low battery capacity condition in a wireless device communicating with the remote device, comprising: monitoring the capacity of the battery wherein a low capacity condition may be detected while the wireless device and the remote unit are in communication; upon detecting a low capacity condition of the battery, sending a low battery capacity status signal to the remote device; and while the battery is in a low battery capacity condition, maintaining communications between the wireless device and the remote device until the low battery capacity condition is corrected, otherwise sending a normal battery level status signal to the remote device.
2. A method as claimed in claim 1 , further comprising the step of placing the wireless device into a standby mode while the battery is in a low battery capacity condition.
3. A method as claimed in claim 1 , further comprising the step of correcting the low battery capacity status during the standby state until a normal battery capacity status is attained.
4. A method as claimed in claim 1 , further comprising the step of correcting the low battery capacity status during the standby state until a normal battery capacity status is attained, and, upon correcting the low battery capacity status of the battery, recommunicating with the remote device.
5. A computer readable medium for causing an information handling system to execute steps for notifying a remote device of a low battery capacity condition in a wireless device communicating with the remote device, the steps comprising: monitoring the capacity of the battery wherein a low capacity condition may be detected while the wireless device and the remote unit are in communication; upon detecting a low capacity condition of the battery, sending a low battery capacity status signal to the remote device; and while the battery is in a low battery capacity condition, maintaining communications between the wireless device and the remote device until the low battery capacity condition is corrected, otherwise sending a normal battery level status signal to the remote device.
6. A computer readable medium as claimed in claim 5 , the steps further comprising the step of placing the wireless device into a standby mode while the battery is in a low battery capacity condition.
7. A computer readable medium as claimed in claim 5 , the steps further comprising the step of correcting the low battery capacity status during the standby state until a normal battery capacity status is attained.
8. A computer readable medium as claimed in claim 5 , the steps further comprising the step of correcting the low battery capacity status during the standby state until a normal battery capacity status is attained, and, upon correcting the low battery capacity status of the battery, recommunicating with the remote device.
